Blue and Round

Approx October of 1975, just near Ft.McClelan Army Base going north on hwy 21 then turned on why 431 north just past the bridge we saw a blue circle in the sky about the size of the moon appears, we where looking south about the blue mountain area, the object just hovered moving slightly in all directions, we then pulled over and got out to look as many others did also still on us hwy 431 right past Chinese resterant which may not have been there at the time.  My grandmother said oh it's just a weather ballon but it wasn't this was bright and after about 15 mins in a instant it either shrink to nothing or went south till it was out of site.  After the Wellborn vs Saks game we got home and it was on 3340 news that several sightings of ufo was reported in this area.  Now I'm of christian faith and don't believe in green Martians but all I know is I seen a  unidentified flying object, could have been pocket of space gas or something from the heavens for all I know.   
A 2nd sighting acurred in same county in Coldwater, Al., Approx 1987 was traveling hwy 202 west almost at c & s service station I looked to the right and seen a round moon shaped white object in the sky I then thought to myself nice full moon tonight then it dawned on me the moon is on the opposite side after a last look at the object I lost it in the tree tops as I was driving never to see it again.
Witness indicates that the date of the sighting is approximate.  PD
